Trying to figure out a fuel system solution for the 900-1200rwhp range. What issues would I be looking at by placing welding in a sump tank and running an Aeromotive Eliminator?

I've never had problems on older fox body mustangs, but not sure how deeply wired the fuel systems goes into the computer. Tried searching for some of the early fuel issue threads, but they were discussing the 600-800hp range which is easily solved with dual pumps.
